Disc Spherical Fuzzy Sets and Their Application in Decision Making

The Circular Spherical Fuzzy Set (C-SFS) idea, an expansion of the C-SFS, is introduced in this article. We also introduce the innovative extension of C-SFSs known as Disc Spherical Fuzzy Sets (D-SFSs). Both C-SFSs and D-SFSs are made up of radially curved Spherical fuzzy values. In the study, basic algebraic and mathematical operations, are established for D-SFSs. The study also suggests the characteristics of innovative D-SF weighted average and geometric aggregation operators. We use the D-SF CODAS approach for multi-criteria group decision-making (MCGDM) in this situation. With the help of this study, circular and D-SFSs will be more widely utilized in decision support systems and related fields.
